Answer 1

To determine the linear and quadratic factors of the expression \(2x^4 + 19x^3 + 35x^2\), we can start by factoring out the greatest common factor (GCF) from the polynomial.

1. **Identify the GCF**:
The GCF of the terms \(2x^4\), \(19x^3\), and \(35x^2\) is \(x^2\).

2. **Factor out the GCF**:
Factor \(x^2\) from the polynomial:
\[
2x^4 + 19x^3 + 35x^2 = x^2(2x^2 + 19x + 35)
\]

3. **Factor the quadratic \(2x^2 + 19x + 35\)**:
We want to factor the quadratic \(2x^2 + 19x + 35\). We can do this by looking for two numbers that multiply to \(2 * 35 = 70\) and add to \(19\). The numbers \(14\) and \(5\) work since \(14 \times 5 = 70\) and \(14 + 5 = 19\).

Now, we rewrite the middle term using these numbers:
\[
2x^2 + 14x + 5x + 35
\]
Group the terms:
\[
= 2x(x + 7) + 5(x + 7)
\]
We can factor out \((x + 7)\):
\[
= (2x + 5)(x + 7)
\]

4. **Combine all factors**:
Putting it all together, we have:
\[
2x^4 + 19x^3 + 35x^2 = x^2(2x + 5)(x + 7)
\]

Thus, the complete factorization gives us the linear factors \(2x + 5\) and \(x + 7\), and the quadratic factor \(x^2\).

The answer to your question is:
**\(x^2(2x + 5)(x + 7)\)**.
